How much heat is needed to raise the temperature of 8g of water by 15oc?

Explanation:

The heat (thermal energy) needed in to raise the temperature in a process can be found using the following equation:

  (1)

Where:

is the heat

is the mass of the element (water in this case)

is the specific heat capacity of the material. In the case of water is

is the variation in temperature  (which is increased in this case)

Knowing this, let's rewrite (1) with these values:

 (2)

Finally:

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
